Samsung Galaxy Watch 4 vs Watch 3: Is it Worth Upgrading?

Galaxy Unpacked was one of the most sought-after events of this month. Samsung introduced their new flagships Galaxy Z Fold3 and the Galaxy Z Flip3. The Korean giant also announced the launch of products like the Galaxy Watch4 and the Galaxy Buds2.

Samsung Galaxy Watch 4 vs Watch 3 Comparison

It seems Samsung is splitting up the Watch series as they did with the Note and S series. There are two main models to choose from, the Galaxy Watch4 and the Galaxy Watch4 Classic. So in this Samsung Galaxy Watch 4 vs Watch 3 guide, we’ll compare both new models to their predecessor, the Galaxy Watch3.

Must Read

As we said, Samsung has split the new Galaxy Watch4 into two, the Watch4 and the Watch4 Classic. According to Samsung, the underlying hardware is the same for both models, and the changes are only on an aesthetic level.

Samsung Galaxy Watch 4 vs Watch 3

Both the Galaxy Watch4 and the Galaxy Watch3 are premium smartwatches that offer the look and feel of an Analog watch, thanks to their circular design. Even though the differences between these watches are subtle, one must better understand these models before buying them.

Models

Samsung offers a range of watches in both these series.

The Galaxy Watch3 series comes with a total of 5 variants to choose from a group of two. There are three models with a 45mm case and two with a 41mm case. The two smaller models and two larger ones use a stainless steel dial. Lastly, a 45mm model uses titanium as the primary material. The 45mm stainless steel models weigh about 53.8g without the straps. Smaller models weigh around 48.2g.

There is a total of 10 models in the new Galaxy Watch4 series. 6 Watch4 models and 4 Watch4 Classic models. The Watch4 comes in two sizes, a 44mm (Black, Green, Silver) and a 40mm (Black, Pink Gold, Silver), with Aluminium as the primary material. Watch4 Classic, on the other hand, comes in 46mm (Black, Silver) and 42mm (Black, Silver) dial sizes. However, the smaller silver model of the Watch4 Classic is lighter to the eye.

Display

Samsung has its way with its displays, and they might be one of the selling points of these watches. Both the Galaxy Watch3 and Galaxy Watch4 use a full color Always On Display.

The larger 45mm models in the Watch3 series use a 1.4 inch (or 34mm) circular Super AMOLED display. These displays come with a resolution of 360 x 360. The smaller 41mm models use a 1.2 inch (30mm) circular Super AMOLED display with the resolution as the larger model. Corning Gorilla Glass DX protects the Watch3, which is a fancy new name for glass that breaks.

The Galaxy Watch3 comes with a rotating bezel and a premium leather strap that fits snugly on your wrist.

Watch4 and Watch4 Classic

Despite their differences, the larger 44mm and 46 mm models in the Watch4 and Watch4 Classic series use a 1.4 inch (or 34.6mm) circular Super AMOLED display. These displays have a significantly higher resolution of 450×450. The smaller 40mm and 46mm models use a 1.2 inch (30.4mm) circular Super AMOLED touchscreen display with a slightly lower resolution than the larger models.

Still, they’re better than the Watch3 series with a resolution of 396×396. The improved Corning Gorilla Glass DX+ used in the Watch4 should offer better resistance to scratches and hits. But keep in mind that they too will break if not handled carefully.

The rotating bezel is now available only for the Galaxy Watch4 Classic. You can get a Watch4 with either a hybrid leather band or a sports band. The Watch4 Classic uses the sports band as default. However, there is a Galaxy Watch4 Classic THOM BROWNE Edition with more styles.

Processor and Memory

According to Samsung, the Galaxy Watch4 packs nearly double the performance compared to the Watch3. Both the models in the Watch4 use the new 5nm Exynos W920. The Dual-core CPU with a maximum clock speed of 1.18GHz with the onboard GPU dwarfs the Dual-core Exynos 9110 used in the Watch3.

As for memory and storage, the Watch4 comes with 1.5gigs of RAM and 16gigs of onboard storage. Yet another improvement compared to the 1GB RAM and 8GB storage of the older Watch3.

Battery and Charging

The Galaxy Watch3 uses 340mAh and 247mAh Li-ion batteries for the larger and smaller models. As for the Watch4 series, the larger 46mm and 44mm models are getting a marginal upgrade with the 361mAh battery, but the smaller ones use the older 247mAh capacity batteries. 

Both the Watch3 and Watch series use a wireless charger. Samsung claims the WPC-based wireless charging on the Watch4 series will improve charging time without compromising battery health. The newer 5nm SoC of the Watch4 might consume less due to its power-efficient design.

Software

Galaxy Watch3 is powered by the Tizen Based Wearable OS 5.5 with the best in class apps and services to help you get through the day. Galaxy Watch4 will use Samsung’s new Android-based Wear OS that uses the One UI Watch 3. You can choose from a wide range of watch faces that transform your watch into a classic or a modern machine.

Connectivity

Both the Galaxy Watch series are LTE devices that use an e-SIM for internet connectivity. Both supports Bluetooth 5.0, Wi-Fi 802.11 a/b/g/n 2.4GHz, NFC, GPS/Glonass/Beidou/Galileo. However, the Galaxy Watch4 also supports 5GHz Wi-Fi.

Sensors and Health Monitoring

The Galaxy Watch4 is a clear winner in this one, with their new BioActive Sensor. The BioActive sensor gives accurate heart rate readings (using both optical and electrical heart rate measuring). Bioelectrical Impedance Analysis is also possible with the BioActive sensor. Watch4 also features an accelerometer, barometer, gyro sensor, geomagnetic sensor, and a light sensor.

Watch3, on the other hand, keeps the user updated on their health by using optical and electrical heart rate sensors. It also packs other essential sensors we find on the new Watch4. 

Water and Dust Resistance

Both generations of the Galaxy Watch offer the same level of protection to water and dust. These IP68 rated watches are water-resistant for up to 5ATM (or 5 meters) and can survive swimming. However, Samsung doesn’t recommend that you take them to exercises like diving.

Android and iOS Compatibility

We don’t know what’s on Samsung’s mind, but we do know this, the new Galaxy Watch4 series is not compatible with iOS. We guess that Apple users prefer the Apple Watch over the Galaxy Watch. If you own an Apple watch already, then the Galaxy Watch3 might be your only choice. 

Is it worth upgrading to Samsung Galaxy Watch 4?

It might not be worth upgrading to a Samsung Galaxy Watch 4 if you already own a Galaxy Watch 3. The two smartwatches are incredibly similar in design and features, except for the new BioActive sensor.

If it is not a deal-breaker for you, then stay with Galaxy Watch 3. The watch’s new features include wireless charging and being slimmer and lighter than the previous model, making it look more elegant on your wrist.

Pricing and Availability

Galaxy Watch3 is now available for purchase for around $349.99 in the US, and we believe the price might come down thanks to the new Watch4. The Galaxy Watch4 will go on sale for around $249. Galaxy Watch4 Classic will be on sale for about $349. The Galaxy Watch4 series will be available from August 27. 

You can pre-order it from the official Samsung Website. It will soon be available on other online marketplaces such as Amazon.

Conclusion

Both the Galaxy Watch3 and Galaxy Watch4 are great wearables, but they are too similar to each other when it comes to design and features. With the exception of the BioActive sensor, there is nothing on Watch3 that we can’t find here in the Watch4. If you’re not worried about having the new BioActive sensor with Samsung’s latest Wear OS, then stick with your Watch3.
